Tongue twisters are great practice for auditory awareness, sound discrimination, and articulation.
Take a chance and bring these inserts to your classroom. The fast repetition of these words may leave your ELL students laughing but surely their English pronunciation will improve. You will be amazed at their responses and level of engagement. They will ask for these cubes all the time. These tongue twisters become a fun part of their lunch break and recess. To your surprise and amusement you will catch the students holding on to the cube and try to copy the different idioms to practice at home.
